Revert unintentional "volatile" changes in ipc/msg.c

2006-11-04T17:55:00Z

Commit 5a06a363ef48444186f18095ae1b932dddbbfa89 ("[PATCH] ipc/msg.c: clean up coding style") breaks fakeroot on Alpha (variously hangs or oopses), according to a report by Falk Hueffner. The fact that the code seems to rely on compiler access ordering through the use of "volatile" is a pretty certain sign that the code has locking problems, and we should fix those properly and then remove the whole "volatile" entirely. But in the meantime, the movement of "volatile" was unintentional, and should be reverted. Cc: Falk Hueffner Cc: Andrew Morton Acked-by: Ingo Molnar Signed-off-by: Linus Torvalds

[PATCH] Fix ipc entries removal

2006-11-03T20:27:56Z

Fix two issuses related to ipc_ids->entries freeing. 1. When freeing ipc namespace we need to free entries allocated with ipc_init_ids(). 2. When removing old entries in grow_ary() ipc_rcu_putref() may be called on entries set to &ids->nullentry earlier in ipc_init_ids(). This is almost impossible without namespaces, but with them this situation becomes possible. Found during OpenVZ testing after obvious leaks in beancounters.

[PATCH] ipc: replace kmalloc and memset in get_undo_list with kzalloc

2006-10-02T14:57:22Z

Simplify get_undo_list() by dropping the unnecessary cast, removing the size variable, and switching to kzalloc() instead of a kmalloc() followed by a memset(). This cleanup was split then modified from Jes Sorenson's Task Notifiers patches. Signed-off-by: Matt Helsley Cc: Jes Sorensen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
